WPF WindowChrome 自定义标题栏时窗体阴影效果设置

即将GlassFrameThickness值设置为"0,0,0,1"，此时即可获得阴影效果，此阴影效果为系统默认（测试系统是Win10）

在MSDN没查到相关说明

备注：在测试中发现将ResizeMode直接写在Window标签属性上而不是以Style.Setter的方式赋值，当值为NoResize时，窗体会无阴影效果

xmlns:shell="clr-namespace:System.Windows.Shell;assembly=PresentationFramework"
<Window.Style>
        <Style TargetType="Window">
            <Setter Property="UseLayoutRounding" Value="True"/>
            <Setter Property="ResizeMode" Value="NoResize"/>
            <Setter Property="shell:WindowChrome.WindowChrome">
                <Setter.Value>
                    <shell:WindowChrome CaptionHeight="80"
                            GlassFrameThickness="0,0,0,1" 
                            ResizeBorderThickness="5" />
                </Setter.Value>
            </Setter>
            <Style.Triggers>
                <DataTrigger Binding="{Binding DataContext.IsHomePage, RelativeSource={RelativeSource Self}}" 
                                 Value="false">
                    <Setter Property="ResizeMode" Value="CanResize"/>
                </DataTrigger>
            </Style.Triggers>
        </Style>
    </Window.Style>
